Research direction

Review the sprintf calls in libs/format/benchmark/bench_format.cpp, including the surrounding buffer and format-string usage. Check the benchmark behavior on macOS Clang and confirm that the deprecated calls are addressed without changing the measured formatting results; the benchmark should build without sprintf deprecation warnings.

Written by the indexing model from the issue text.

Description

sprintf is deprecated on macos clang.

"Use snprintf if available as some compilers (clang 14.0) issue deprecation warnings for sprintf"

sprintf appears in these files:

libs/format/benchmark/bench_format.cpp:// bench_variants.cc :  do the same task, with sprintf, stream, and format
libs/format/benchmark/bench_format.cpp:    // Check that sprintf is Unix98 compatible on the platform :
libs/format/benchmark/bench_format.cpp://      (e.g., it expects sprintf to be POSIX compliant)
libs/format/benchmark/bench_format.cpp:#include <cstdio>  // sprintf
libs/format/benchmark/bench_format.cpp:      sprintf(buf, fstring.c_str(), arg1, arg2, arg3);
libs/format/benchmark/bench_format.cpp:    sprintf(buf, fstring.c_str(), arg1, arg2, arg3);
